The instructions are to decrease as you have been doing at the armhole edge for the raglan sleeve and at the same time, decrease at the neck edge.
So when you get to the neck edge, turn, decrease (bind off) 7 sts, work to the end of the row, turn, work the armhole decrease, and work to the neck edge, turn decrease 5 sts, work to the end of the row, turn, work the armhoe decrease, and keep alternating the decreases at the armhole edge with a decrease at the neck edge so that you have a stairstep decreae at the neck edge on alternate rows. Altogether you will have decreased 24sts in stairstep fashion.

ok that makes sense! wish the pattern would just say to turn and bind off... thnaks for your help!
